Professor Bruck Receives IEEE Data Storage Best Paper Award

03-19-15

Jehoshua Bruck, Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical Engineering, and colleagues' paper entitled “Zigzag Codes: MDS Array Codes With Optimal Rebuilding” has received the 2013 best paper award from the Data Storage Technical Committee of the Institute of Electrical and Electronics Engineers (IEEE). The award recognizes a paper that has substantial and meaningful impact on both the theory and the practice of the existing or future data storage systems, or on emerging storage technologies that are gaining momentum. By giving these awards, the committee also motivates researchers to continue to make great original contributions to the field of data storage.

What Is Possible in Real-World Communication Systems

09-29-14

Victoria Kostina, Assistant Professor of Electrical Engineering, is the newest member of the EE Department.  When asked what excites her about research in information theory she states “ I love that it is very basic research, very theoretical. Once we strip away all the particularities of a given problem, we are left with a mathematical model, which is timeless. Once you solve such a problem, it stays there. But at the same time, I like that this work applies to the real world. The fact that it gives us insights into how to improve existing communication systems is a very exciting feature for me.” [Interview with Professor Kostina] [ENGenious article]

Variability Keeps The Body In Balance

09-22-14

By combining heart rate data from real athletes with a branch of mathematics called control theory, John Doyle, Jean-Lou Chameau Professor of Control and Dynamical Systems, Electrical Engineering, and Bioengineering and colleagues have devised a way to better understand the relationship between reduced heart rate variability (HRV) and health.

"A familiar related problem is in driving," Doyle says. "To get to a destination despite varying weather and traffic conditions, any driver—even a robotic one—will change factors such as acceleration, braking, steering, and wipers. If these factors suddenly became frozen and unchangeable while the car was still moving, it would be a nearly certain predictor that a crash was imminent. Similarly, loss of heart rate variability predicts some kind of malfunction or 'crash,' often before there are any other indications," he says. [Caltech Release] [Read the Paper]

Programmed to Fold: RNA Origami

08-20-14

Paul Rothemund, Senior Research Associate in Bioengineering, Computer Science, and Computation and Neural Systems, and colleagues have fabricated complicated shapes from DNA's close chemical cousin, RNA. "RNA origami is still in its infancy," says Rothemund. "Nevertheless, I believe that RNA origami, because of their potential to be manufactured by cells, and because of the extra functionality possible with RNA, will have at least as big an impact as DNA origami."

Coding Breakthrough Could Accelerate Mobile Network Speeds

06-02-14

Tracey C. Ho, Assistant Professor of Electrical Engineering and Computer Science, and colleagues’ research on stateless data transmission using Random Linear Network Coding (RLNC) promises higher network speeds with an elegant mathematical approach to data error correction and redundancy. They have shown that data could be transmitted without link layer flow control bogging down throughput with retransmission requests, and also the size of the transmission can be optimized for network efficiency and application latency constraints.

Celebrating with Professor Carver Mead

05-02-14

Carver Mead, Gordon and Betty Moore Professor of Engineering and Applied Science, Emeritus, celebrated his 80th birthday on May 1, 2014. Professor Mead is best known for his pioneering work on VLSI (very-large-scale integration) circuit technology in the 1970s and 1980s, which made it possible to greatly increase the number of transistors placed on a single semiconductor chip. It is no exaggeration to say that the computer era we live in would not have been possible without VLSI technology. He remains as passionate today about science and engineering as he ever was. "There isn't really a time when you're too old to have new ideas," Mead says. [Caltech interview] [Share Your Memories] [ENGenious article]

Bending the Light with a Tiny Chip

03-10-14

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, and colleagues have developed a new light-bending silicon chip that acts as a lens-free projector--and could one day end up in your cell phone. They were able to bypass traditional optics by manipulating the coherence of light—a property that allows the researchers to "bend" the light waves on the surface of the chip without lenses or the use of any mechanical movement.

A New Laser for a Faster Internet

02-26-14

Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering, and his group have developed a new laser that has the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network—the backbone of the Internet. "What became the prime motivator for our project was that the present-day laser designs have an internal architecture which is unfavorable for high spectral-purity operation. This is because they allow a large and theoretically unavoidable optical noise to comingle with the coherent laser and thus degrade its spectral purity," Professor Yariv describes. [Caltech Release]
